摘　　要：本文分析了利用强度自相关和干涉自相关信息获取超短光脉冲形状和啁啾特性的方法及其缺陷。提出了一种直接测量超短光脉冲幅度谱和相位谱的原理和测量装置，并对锁模脉冲进行了测量。然后由逆傅里叶变换即可得到脉冲时域特性（脉冲形状和宽度），且由相位谱可得超短脉冲的各阶啁啾系数。This paper describes the principle and defect of measuring the shape and chirp of the ultrashort optical pulse by means of intensity autocorrelation and interferometric autocorrelation,and proposes a theory and an apparatus for directly measuring the amplitude and phase spectra.The mode-locked pulse is measured by this method.The shape and width of the pules can be accurately retrived by a Fourier transform.The chirped parameters can be got from the phase spectrum.

关 键 词：超短光脉冲 脉冲形状 脉冲宽度
